apt-get update stalls when accessing dualstacked ipv4 + ipv6 mirrors

[Deeps]

Binary package hint: apt

Description: Ubuntu 8.04.2
Release: 8.04
Package: apt 0.7.9ubuntu17.1
Mirror: gb.archive.ubuntu.com
gb.archive.ubuntu.com has address 194.169.254.10
gb.archive.ubuntu.com has IPv6 address 2a01:450:10:1::10

Have an entry in /etc/network/interfaces defined as follows:

#IPv6
auto he6
iface he6 inet6 v4tunnel
        address 2001:470:1f08:xxx::2
        netmask 64
        endpoint 216.66.xx.xx
        ttl 255
        #up ip link set mtu 1280 dev he6
        up ip route add default via 2001:470:1f08:xxx::1 dev he6

When bringing up with 'ifup he6', or at boot time, the interfaces comes up successfully, and apt-get update will happy update from a mirror that has a dualstacked hostname (like gb.archive.ubuntu.com). If for any reason the he6 interface is taken down, when it is brought up again, apt-get update will timeout trying to access dual stacked hosts, while ping/ping6 to the host will work, as well as wget with or without any -4 or -6 switches.

Update: problem is resolved after rebooting the system, but this isn't ideal; after reconfiguring eth0 a reboot isn't required to carry on using apt on ipv4...

This sounds like bug #417757?

Does this problem still exist on newer Ubuntu releases?
